Abstract
A method for data exchange with a mobile asset including the step of comparing the quality of the communication link to a predetermined value prior to initiating the communication. Polling of a fleet of mobile assets may be scheduled by considering a map of the communication link quality along the route of the mobile assets. An optimal packet size may be selected for the data transfer by considering the quality of the communication link.
Claims13
A method of data exchange with a mobile asset moving along a route, the method comprising;
- determining the quality of a respective communication link for each of a plurality of segments along the route;
- determining the position of the mobile asset along the route;
- initiating operation of the communication link for data transfer with the mobile asset only when the communication link quality in the segment including the position of the mobile asset exceeds a predetermined value.
A method of data exchange with a mobile asset moving along a route, the method comprising:
- determining a communication link quality for each of a plurality of segments along the route;
- determining the segment in which the mobile asset is located;
- initiating the operation of a communication link for data transfer with the mobile asset;
- and
- selecting the packet size for the data transfer as a function of the communication link quality for the segment in which the mobile asset is located.
A method of scheduling the polling of a plurality of mobile assets over a communication link, the method comprising:
- defining a plurality of geographic segments, each segment having a quality associated with a communication link;
- scheduling the polling of a plurality of mobile assets for data transfer to occur via the communication link for each asset in a segment having communication link quality above a predetermined value.
A method of mapping the quality of a communication link over a route of a mobile asset, the method comprising:
- installing a global positioning system on a mobile asset;
- installing a sensor for measuring a communication link quality on the mobile asset;
- recording on-board the mobile asset the communication link quality as a function of location at a plurality of locations as the mobile asset moves along a route to define a file of signal quality data;
- transferring the file to an off-board database;
- and
- analyzing the database to generate a map of the communication link quality over the route.
